843626 divided by 18 
Let's see how many times 18 fits into 843626.

Moving on to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 18

Advancing to step 2:
If we divide 84 by 18, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 72 from 84, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Let's proceed to step 3:
18 can be fit into 123 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 108 from 123 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

Step 4:
18 goes into 156 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 468.0
Subtract 144 from 156 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 18

Advancing to step 5:
122 divided by 18 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 4686.0
The remainder is 14 after subtracting 108 from 122.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 18

Advancing to step 6:
When dividing 146 by 18, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 46868.0
The remainder is 2 after subtracting 144 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 18, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 46868.1
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 46868.11
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 46868.11, with a leftover of 0.002.
